I don't use glass with my pottery but I have access to a quantity which contains bauxite so would really like to use it in some of my pieces, especially the handbuilt trays. This one I threw into the bisque and I vaguely remember glass should only go to 800C so this was a little higher and the crazing is wonderful but it would not make the piece user friendly as I can feel the edges of the larger crazes. I am hoping someone out in blogger world or on the ceramics discussion list will be able to give me an idea of the firing temps and cooling to make the pieces useable.
